LUBRICATOR.

Specification of Letters Patent No. 29,515, dated August '7, 1860.

To all whom 'it/mcy concern:

Be it known that we, EDWIN PARKER, BENJAMIN PARKER, and T. S. PARKER, all of Schenectady, in the county of Schenectady and State of New York, have invented a new and Improved Lubricator for Journals, &c.; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a plan view of the lubricating mechanism arranged for oiling the journals of shafting. Fig. 2, is a side elevation of the mechanism for transmit-ting motion from the, shaft to the oil cup, and a diametrical section through the oil cup and oiling Y tubes.

Similar letters of reference indicate corresponding parts in both figures.

The object of this invention is to produce an oil cup which, in connection with certain mechanism, will keep up a regular supply of oil to the journals of shafting, or to the slide rest of steam engines, or to friction surfaces generally whether they have a reciprocating or rotary motion whereby a great saving of oil over the present oil cups will be obtained, as the supply of oil will be automatic, at the same time it may be regulated according to the amount of friction surface or the speed at which the parts are moving; and the lubricating liquid may then be supplied only as fast as it is consumed and required.

To these ends our invention consists in arranging in an oil reservoir of a suitable capacity, a plug or stem with a perforation through it, in such a manner that by rotating the oil reservoir said perforation will receive oil from the cup and discharge this oil on the surface to be lubricated, the motion of the oil reservoir being made dependent upon the motion of the shaft, or whatever movable object it is desired to lubricate, so that when the prime mover stops the supply of oil will cease, all being constructed and arranged as will be hereinafter described and represented.

' To enable those skilled in the art to fully understand our invention we will proceed to describe its construction and operation.

Our invent-ion is intended to be applied to stationary journal boxes for all horizontal shafting, also the cross heads of steam engines, or other parts of machinery requiring A, is an oil cup or reservoir which may be made of any desirable capacity, that consists of a. cylinder and a base a, and cap Z), which latter are secured to each end of the cylinder by a central screw rod c. The base portion a, has a neck d, with a circular recess formed in its bottom into which lits a plug B.

e, is a hole that is drilled through the solid portion of the neck d, and g, is a hole that passes down through the plug B. These two holes e and g are so arranged that at each revolution of the cup A, which is effected as will be herein after described, a communication will be formed through these holes from the oil cup to the journal to be oiled, or as the case may be, and in this way the supply channels will be opened and closed alternately as the cup A, rotates upon the fixed plug B.

C is a large ratchet wheel that is keyed to the lower end of the neck d, and D is a worm screw that engages with teeth of this wheel C. The worm screw D is on one end of a shaft D, that carries on its opposite end a long toothed ratchet wheel E, that is rotated by a striker L, projecting from the shaft F, of a friction wheel G, and this friction wheel Gr, is hung in bearings on the end of a bar H, so that the wheel will be allowed to act by its own gravity on the surface of the shaft, (shown in red lines) to be oiled in its bearings by the cup A. The plug B, is to be screwed into the cap of the journal box and the cup is to be rotated by the shaft, of which the journal is to be oiled, through the medium of friction wheel G, striker ratchet wheel E, worm screw D, and wheel C, which may be 4arranged in any convenient manner over the shaft.

When it is desired to apply the oil cup to parts of machine that have a rectilinear reciprocating motion, the friction wheel with its ratchets and worm wheel are removed and a simple pawl bar J, Fig. 1, is used Which actuates a ratchet Wheel K, that is keyed to the neck ai, of the oil cup, at eachA movement of the piece of machinery to which the cup may be attached, in consequence of the bar J, striking some stationary projection.

Now from this description it will be seen that in either instance of the application of our self oiling cup, that at each revolution, or if necessary semi-revolution, of the oil cup, the oil Will escape in small quantities, at regular intervals, as long as the motion 0f the machinery is kept up and supply the surface to be oiled, With oil only so fast as the oil is consumed.

Having thus described our invention, What We claim as new and desire to secure by Letters Patent is-
